. 'ljhis invention relatesto certain new and useful improvements in water motors of the type to be placed in thefpath of flow of a streamrof water or waterfall with the water rotating' turbine wheels with 'powerl taken from the shafts thereof and has forits pri# mary obj ect to provide novel devices for controlling the operation of the water. wheels and for holding them stationary while a stream of water flows 'thereover when it is desired to place the motor out of use.y

lWith the above and otherobjects in View that will become apparent as the nature of the invention is better understood, the same consists in the novel form, `combination and arrangement f parts hereinafter more fully described, shown in the accompanying drawings and claimed.

, In the drawings e Y Figure 1 fragmentarily illustrates a con'- crete base or support for a water motor thatv Ais shown in side elevation and partly broken away;

- Figure 2 is a vertical longitudinal sectional view through the water-motor and concrete supportingbase showing the water operated wheels of the nmotor and the brakeshoes for arresting movement thereof ;Z d i Figure 3 is a horizontal sectional View taken on line 3-3 of Figure v1 showingithe eX'teriorly positioned operating mechanism for the water wheel brake shoes; I

Figure 4 is a detail sectional view taken on line 4-4 of Figurev `2 showing the interior worm gear mechanism for raising the brake shoes; and n Figure 5-is a detail sectional view takenon line 5-5 of Figure 4 showing the vertically shiftable screw attached tothe brake shoes and operated by thewormgear mechanism.

The water motor is adapted to be posi# tioned for intercepting the flow of a-stream of water, such as a river or waterfall and is mounted upon and partially embedded in a concrete base or foundation 1, the motor comprising la casing structure including a hori- Zontal plate 2 anchored to the upperend of the hollow foundation 1 by bolts 3 set into the concrete and carrying a side .platform 4 projecting laterally of the concrete foundation 1929.

as' shown in Figure 2 andbraced atits outer i end by the inclined brace bars 5. Themotor casing further includes a rectangular wall 6 depending'from the plate 2 and set into the hollow lfoundation ,a 1 with the lower send thereofY flanged outwardly f and 'extending into a pocket 7 ,formed inthe inner face 0f the hollow foundation, the wall 6 lbeing juxtaposed `to theY wall -of the L foundation f as shown in Figure 2. The, casing section Sie-X.- tending above vthe plate 2 is-reversely curved inwardly, and then outwardly as at 8a on the arc vof a circle andi-s provided ywith an edge flange 9the end wallsof the lupper casing section being curved while theside walls Y l() extend vertically and `are'parallel with each other as shown in Figure 3. Atop sec;r tionfasI shown in Figures l and 2gcomprises straight side wallsy and curved end walls, 11

flanged at their lower ends as at 12 to engage theilanges 9 to be'bolted thereto as at 13, the curved walls 8a and 11A cooperating to -form endchambers 14 on thearc of a circle as illus.- trated. The upper ends of the curved -walls 11 are directed inwardly and terminate at points spaced from each other with upwardly curved walls 15 forming end wallsofa receptacle 16 at the upper endof the mOtQr casing to receive water from a lstreamer falls. .The motor casing in alignment with 'ther'wall 6 is providedfwith an, interior, casting com.-

prisin'g `end walls 17 extendingI .transversely of lthe `casing and joined with 'the side walls ftoform water passages 18, the lower ends ofthe walls 17 being flanged inwardly `.as illustrated -in Figure 2. The upper endsof the walls 17 are connected by the head-plate .19 extending transversely ofthe casing walls `6 as shown in Figures 2 and 4.V

The 'outlet for the water motor includes a pipe 2O forked at its upperend as at 21 delining passages communicating with `thepassages 18, an innerwall'22 flanged 'to meet'the lower 'llanged end of the wall 17 and to be vbolted thereto as at23, and an outer wall 24 outwardly flanged at its upperl end to :meet with the llange upon the, lower end ofthe wall 6 and bolted :thereto as at 25. yA lilling of concrete is indicated at 26 andextends from the foundation 1 throughthe wa11s'17 lOO S l wall32" shown in Figure'3 and of ashape and 22 for further anchoring and supporting y the motor casing. Water entering the chamber is directedby the curved bottom wall 15 thereof through the motor casing and is separated byv devicespresently to be de scribed and discharged through `the side passages 18,21 and outlet 20. i e j- A pairk of water wheels comprising Vend disk'walls 27 and radially curved connecting blades 28 has its hub 29 rfixed to the shaft 30 mounted in the side walls of the casing above the mounting plate 2, each water wheel being mounted concentrically within the curved Y' end casing walls 8"and 11, the spacedmeeting edges of the two water wheelsbeing disposed centrally of the bottomoutlet 31: in the hopper `16 as shown in Figure V2. i l

Y The 'water' wheeljshafts 30 eXtendjout- Wardly'through one side wall 10 of the motor casingand into a compartment formed by the in side elevation as illustrated in Figure 1 defining substantially circular communicat- Y Iing'chamliers33V A gear wheel 34 is fixed tothe projecting end of each shaft within the chambers 33 and mesh with each other as shown in Figureil, the meshing gear wheels l 34 upon the shafts 30 insuresteadyand even rotation ofy the fwater'whee'ls 27 and power is Vtaken off the shafts 30 Afor'any purpose desired,"v suchas for the purpose of operating generators. Y. p 1 A pair ofbrake shoes is associated with the two water wheels'for, arresting movement thereof when it is desired to place the motor out of use, together with means for Amoving the ,brake shoes, from koperative to inoperative position. The brake shoes 34 are inl the form of curved plates,.shown more clearly in Figure `2, Y' normally' 'concentric with l and spaced from the peripheral edges of the'water wheels, the brakeshoesv being hingedly connected together at their upper ends as at 35,

j with the en'ds'of the rodforming the hinged connection extending into vertical slots 36 formedin the Vside 'walls 10 Vof the ffmotor casing. YThelower end of eachrbr'ake shoe 34 carries'an end projecting rodextendinginto anglefslots 37 in'thefwalls 10 so that'when the `brake shoes are elevated, their Yupper f hinged ends move upwardly ,between the water wheels while the. lower ends ofthe lbrake shoes move upwardly and in a direction Y toward the peripheral 4edges'of the waterV wheelswith the brake shoes moving into engagement therewith for-arresting movement Y thereof.

VThedevicesfor operating the brake .shoes include apair of screw Vrods 38, centrally disposed beneath the upper hinged edges of the shoes, one'at eachv end thereof and having a linklv connection 39 with the shoes, the lower endof ,the screw depending into a cylinder or pocket A40 depending from the top Vwall 19 'i of 'the' inner casting wall' 17 as shown in Figures 2 and 5.`V kA worm gear 41isthreaded on the upper end ofV each screw y38and isV 'maintained against rlongitudinalfmovement` n f on the screw Vby-the bracket .forks 42 engaged 7. i

with the YKcollar 43 depending from the worm gear`41. Theshaft44 hasa pair of'worms 45 fixedthereto,jeach worm engaged with one of the gears 41 while the shaft 44 extends casing as shown in Figures 1 and 4. A bevel gear 46 upon"theextended end of the shaft 44 meshes with a bevel gear 47 upon the shaft at` one end through the'side wall of the motor 48 journaled in brackets L49 upon the plate 2v and platform 4. The Vother end of the shaft 48 carries a bevel gear 50 meshing with the bevel gear 51 uponthelower end of the vertical shaft 52 journaled in the standard 53 and having a hand wheel 54 .upon its upper end.v When it is desired to arrest rotation of the water wheels, the chain of shafts and gears is operatedV by the Vhand wheel 54 eXeriorly of the motor casing for raising the brake shoes 34 that are guidedby their rod eXtensions in the slots 36 and 37, the shoes movingV Y i upwardly into engagement with the edges of the water wheels for arresting movement thereof. Water will then flow into the hopper 16 from a river or falls and aroundv the outer edges ofthe water wheels` through the spaces'14 and discharged-through the I 'passagesjlS and21 tothe outlet 20. When the bralre'shoes are lowered by the shaft and 'j vention, it is'nevertheless to be understood thatniinor changes may be made therein 'without departing from the spirit andl scope of the invention as claimed. f
